Reshoring critical metal production

YC S25

About the Company

We’re working to produce the most profitable light-weight metals in the world, here in the US, and carbon neutrally. We’re doing this by leveraging existing chlorination and electrolytic technology, while designing a novel molten materials process that takes byproducts from the metal production process and creates critical feedstock and high value coproducts. We are located in Alameda and are building our pilot plant for operation in the Bay Area Q2 2026.
